Airtac MAC Stainless Steel Mini Air Cylinder MAC32X125SCMH
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC32X125SCMH is a genuine double acting + cushion standard round-body mini air cylinder with a Ø32mm bore and 125mm stroke, 1/8" air ports and a stainless-steel barrel with a hard-chrome-plated rod for reliable, mildly corrosion-resistant service. A variable air cushion at both ends lets you tune end-of-stroke deceleration on site.

About the Airtac MAC Stainless Steel Mini Air Cylinder MAC32X125SCMH
Stroke dominates this build: 125 mm of travel on a 32 mm bore, enough to swing a gate, extend a pusher or index a fixture across a wide span. In force terms expect 402 N forward and 345.6 N back at 0.5 MPa, climbing to 563 N and 483.8 N at 0.7 MPa. Movement is double acting - pressurised air drives both directions - and needle-adjustable cushions at each end soak up the stop, so loads can travel at 30-800 mm/s without banging the covers.
Its round body is a riveted stack: stainless-steel barrel, aluminium covers and a stainless block rolled into one leak-tight unit, with the carbon-steel rod hard-chrome plated to 20 um against rust and scoring. Every MAC leaves the factory magnetised, so CMSG / DMSG / EMSG switches mount without ordering a special piston. Practical sizing: treat 241 N (about 60 percent of push) as the working force at 0.5 MPa, which corresponds to roughly 20 kg lifted vertically with a 2:1 safety factor.

Specifications follow the official AirTAC MA-series datasheet. Barrel: stainless-steel tube (round-body, riveted rolling-packed construction); piston rod: carbon steel with 20µm hard-chrome plating; covers: aluminium alloy. Thread options: PT (blank) / G / NPT. Every MA-series cylinder ships with a built-in magnet for CMSG / DMSG / EMSG position sensors.
Theoretical Output Force (Ø32mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 402 N | 346 N |
| 0.7 MPa | 563 N | 484 N |
| Max (@1.0 MPa) | 82 kgf | |
Actual usable force is lower than theoretical due to friction and back-pressure. Size with a safety margin.

Where the Airtac MAC Stainless Steel Mini Air Cylinder MAC32X125SCMH Is Used
Gate actuation on a bottling line
A diverter gate swings every few seconds as bottles change lanes; 402 N at 0.5 MPa gives ample margin, and the adjustable cushion keeps the gate from slamming its stop.
Pusher on a carton case packer
Cases slide 125 mm into a magazine; the chrome-plated 12 mm rod copes with corrugated dust, and a DMSG switch confirms full extension before taping starts.
Lid press on a small assembly cell
Snap-on lids press home with up to 563 N at 0.7 MPa; working at about 241 N leaves headroom for the pressure dips common on shared plant air.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC32X125SCMH the Right Cylinder?
Compared across the family, a 25 mm bore gives only 245.3 N push at 0.5 MPa and a 40 mm bore gives 628.3 N, so 32 mm sits mid-pack - strong enough for most fixture work without paying for the next size. Air supply runs 0.15-1.0 MPa (22-145 psi) with proof at 1.5 MPa (215 psi). At 125 mm of stroke, side loads on the 12 mm rod invite bending, so guide the load externally rather than letting the rod carry it. The CM round-end back cover suits flat fixed mounting; note that the trailing H in this code is not part of the standard MAC ordering list, so confirm its exact meaning from the datasheet before ordering.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT / G / NPT)
- ✓ Magnet (-S) is standard for sensors
- ✓ Back cover (CA/U/CM) & mount (FA/LB/SDB)
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Avoid side load on the piston rod.
- check Do not dismantle the riveted front/back covers.
- check On first run, back off the cushion screws and release gradually.
- check Installation by qualified personnel per AirTAC docs.
Airtac MAC Stainless Steel Mini Air Cylinder MAC32X125SCMH FAQ
Bore 32 mm: push 402 N and pull 345.6 N at 0.5 MPa; push 563 N and pull 483.8 N at 0.7 MPa; theoretical peak 82 kgf at 1.0 MPa. Stroke is 125 mm, the 12 mm rod threads M10x1.25, and both 1/8" ports take PT taper fittings.
Back both cushion needle screws fully off at first run, then close them gradually until the stop feels soft at any speed in the 30-800 mm/s band. Because a long rod flexes, carry side loads on an external guide. The cylinder itself is a riveted round-body stainless build, and the factory-fitted magnet works with CMSG / DMSG / EMSG switches out of the box.
